Its been a really bad day today. My performance in round #218 was disastrous. My brain was almost shut down for the first hour. Then somehow it started working (but not as efficiently as I wanted). I made my first submission at the 58 minute mark to the A problem. (Yeah, you can call me a n00b. I earned it.) Then inspiration struck for the B problem and I quickly coded it. But I overlooked a critical condition which led to my solution being hacked. Needless to say I didn't try any other problems. I was more keen on hacking others' problems for the last 30 mins.
After my solution B was hacked, I quickly realized what went wrong. After the end of the contest, I resubmitted the solution and it got Accepted. All I had to do was to put a simple if block. :(
